Answer:

x = -9,1

Step-by-step explanation:

f(x) = (x + 4)^2 - 25

Set the function equal to zero

0 = (x + 4)^2 - 25

Add 25 to each side

25 = (x + 4)^2 - 25+25

25 = (x + 4)^2

Take the square root of each side

±sqrt(25) = sqrt( (x + 4)^2 )

±5 = x+4

Separate into two equations

5 = x+4    - 5 = x+4

Subtract 4 from each side

5-4 = x+4-4    -5-4 = x+4-4

1 = x                 -9 =x
